Hose clamp and closing tool
US-A-4,312,101 discloses a hose clamp which, after having been applied to the hose/nipple connection to be sealed, is tightened by deforming an ear provided in the clamp. To prevent the hose from entering the ear dur- ing tightening and thereby being lifted off the nipple, the known hose clamp is provided with an insert made of band material which is inserted into the clamp so as to bridge the gap of the ear.
While an easily deformable steel according to DIN 1.4301 having a typical thickness of 0.6 mm is used for normal hose clamps, specifically clamps of the above-described type with an ear that is to be tightened, inserts are made of an essentially thinner material, typically steel according to DIN 1.4310 with a thickness of 0.2 to 0.4 mm which has high resiliency and high stiffness, is correspondingly difficult to deform and is therefore unsuited for ear clamps. - The present invention is based on the idea that a band material, which is typical with such inserts for known hose clamps, is used for manufactur- ing the hose clamps themselves. In this way, the same starting material is used for an additional purpose, resulting in a saving of cost. In doing so, it is principally possible that finished inserts, which are intended for use with known hose clamps and are cut and formed to the shape provided therefor, are employed for making hose clamps according to the invention.
The embodiment set forth in claims 2 and 3 is advantageous for the stiffness of the hose clamp. The cross-sectional shape of claim 4 or 5 pro- vides a hose clamp with an intrinsic prestress which is not only advanta- geous for compensating tolerances but also ensures the hose clamp to resil- iently engage the hose when the hook in inserted in the opening.
The measure of claim 6 results in the hose clamp being easy to close.
The structures set forth in claims 7 and 8 result in a hose clamp of low profile without any parts projecting far radially outwardly.
A typical field of application of the hose clamp according to the inven- tion is set forth in claim 9.
The gripper-type tool recited in claim 10 is particularly suited for clos- ing the hose clamp according to the invention. This tool permits performing
J, the closure by means of a simple gripper movement with the hook engaging # the opening.
The measures set forth in claims 11 and 12 are suitable in that they ensure a uniform closure of the hose clamp to a cylindrical ring.
The embodiment of the tool according to claims 13 and 14 ensures that the hose clamp is engaged by the tool over its entire circumference.
The features of claims 15 and 16 are of advantage in that they safely prevent canting during closure, which could result in deviations of the finished, closed hose clamp from the cylindrical shape.
A preferred embodiment of the invention will now be explained in more detail with reference to the drawings. In the drawings,
Fig.1 shows a hose clamp in the open condition,
Fig.2 shows the same hose clamp in the closed condition,
Figs. 3a to 3c represent cross-sections through the hose clamp,
Fig. 4 illustrates an open tool with an open hose clamp inserted, and
Fig. 5 shows the same tool in the closed condition. : According to Fig. 1, the hose clamp consists of an open band ring 10 of steel according to DIN 1.4310, which is pre-bent such that the band ends 11, 12 overlap each other. A rectangular opening 13 is punched from the outer overlapping band end 11 while a hook 14 is formed in the inner band end 12 by partial punching and pressing out of the band material. The closed condition of the hose clamp represented in Fig. 2 is ensured by the hook 14 engaging the opening 13.
The thickness of the band material is at most 0.4 mm, preferably 0.3 mm; its width is typically between 5 and 12 mm, and is preferably 8 mm.
Such a band material is suitable specifically for hose clamps which, in the closed condition shown in Fig. 2, have an inner diameter of up to 20 mm, preferably between 3 and 13 mm. The maximum diameter may be over 20 mm if suitable closing means (grippers) are available.
As shown in Figs. 1 and 2, the band ring 10 has a centre portion 15 which takes the substantial width of the ring, and outwardly raised border regions 16. With a total width of the band ring 10 of 8 mm, the width of each raised border region 16 is approximately 1 mm.
a
The amount by which the outer edges 17 of the band ring 10 project beyond its centre portion 15 corresponds at least to the thickness of the band material.
The hook 14 has its open end bent out of the band ring 10 by an amount which is somewhat larger than the thickness of the band material.
This ensures a safe anchoring of the hook 14 at the corresponding edge of the opening 13 in the closed condition of the hose clamp.
The outwardly raised border regions 16 serve not only to increase the stiffness of the band ring 10; their effect is also that the hook 14 in the engaged condition does not project beyond the outer profile of the band ring 10, thereby reducing the chance of the hook 14 to become inadvertently dis- engaged from the opening 13, resulting in the hose clamp to open. Further, the outwardly raised border regions 16 serve for the mutual guidance of the two and ends until the hook 14 snaps into the opening 13. Finally, the raised border regions 16 are also of advantage in that sharp edges are avoided which could cut into the hose to be sealed.
The outer overlapping band end 11 is chamfered at both sides, as ~ shown at 18 in Figs. 1 and 2, in such a way that the terminal edge 19 has a length which substantially corresponds to the width of the centre portion 15 of the band ring 10. The chamfers 18 serve for better guidance and centring during bending and closing of the hose clamp.
The band ring 10 shown in Figs. 1 and 2 has the cross-section repre- sented in Fig. 3a in which the centre portion 15 is cylindrical. Alternatively, as shown in Figs. 3b and 3c, the region 15', 15" may be provided with an outwardly convex or concave curvature to give the band ring 10 an elasticity reserve. As a result of this, the hose clamp is easier to close and, after hook- ing, resiliently engages the hose to be sealed. At the same time, the clamp is less critical to tolerances.
The tool 20 represented in Figs. 4 and 5 for closing the hose clamp shown in Figs. 1 and 2 is in the form of grippers, the jaws 21, 22 of which, in the closed condition represented in Fig. 5, constitute a practically uninter- rupted cylindrical inner surface with a diameter corresponding to the outer diameter of the closed clamp 10.
In cross-section, this inner surface is shaped complementarily to the outer surface of the clamp 10; in other words, the inner surfaces of the jaws 21, 22 have a cylindrical centre portion with enlarged border regions. This
. a complementary shape not only ensures that the hose clamp 10 is completely closed; it also causes the hose clamp 10 to be centred and aligned during closing.
The tips 23, 24 of the jaws 21, 22 are reduced to half the width of their main portions so that they overlap each other in their closed condition. This avoids an interruption of the cylindrical surface of the jaws 21, 22 surround- ing the hose clamp in the closed condition of the tool 20.
The gripper arm 25 carrying the jaw 21 is formed with two legs in the region of the pivot pin 26, and the gripper arm 27 carrying the jaw 22 crosses the arm 25 between the two legs thereof. This avoids canting with the result that the jaws 21, 22 close precisely to the said cylindrical shape.
In a modification not shown in the drawings, the tips of the jaws may : be shaped such that one of them has a central tine which in the closed con- dition engages between two outer tines provided on the other jaw. This structure also avoids canting.
In order to close hose clamps of different diameters using the same grippers, the jaws may be exchangeable, with a corresponding pair of jaws being used for each hose clamp. As an alternative, the jaws may be provided with prismatic inner surfaces. a
The embodiment described above with reference to Figs. 4 and 5 relates to a special tool designed specifically for closing the hose clamp of
Figs. 1 to 3. For the same purpose, commonly available pipe wrenches with adaptable diameters may be used, such as grippers common in the electrical field which have exchangeable half-shell shaped jaws that can be selected in accordance with the diameter of the hose clamp.
